Description

A kind of inner liner stainless steel fitting pipe
Technical field
The utility model is related to technical field of pipeline connection, specifically a kind of inner liner stainless steel fitting pipe.
Background technology
Flange for the pipeline of connection is cirque structure, the inner round portion of usual annulus be used for and cross-section of pipeline or Outer surface is welded, and outer perimeter section is used to fix two flanges, so as to realize the connection of two pipelines.Flange connections are for pipe A projection being relatively large in diameter can be formed for road, there can be inconvenience when pipe laying.When for the logical of pipe laying When bore dia is almost identical with outer diameter tube, the pipeline with raised flange is just difficult to placement and entered, and can only first place pipeline Welded flange again, and Site Welding operation is there is also inconvenience and uncertain factor, welding effect can be become negatively affected, and it is dismounted Also more inconvenient, sealing is also difficult to ensure that.When flange of the prior art is used for pipeline connection, positioning is inconvenient, Er Qieyi As flange buckling deformation occurs during permanent use.
Therefore, for overcome the shortcomings of above-mentioned technology design it is a it is simple in construction, dismounting and easy for installation, sealing A kind of inner liner stainless steel fitting pipe that is good, being less prone to buckling deformation, exactly inventor's problem to be solved.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of inner liner stainless steel fitting pipe, its Simple in construction, dismounting and easy for installation, good airproof performance are less prone to buckling deformation.
The utility model solves the technical scheme that its technical problem used:A kind of inner liner stainless steel fitting pipe, It includes accessory body, flat shoulder grafting head, clamp nut, sealing ring, and the bellmouth termination both sides of the accessory body are respectively arranged with Boss, the outside the boss surface and external screw thread bellmouth are provided with flat shoulder grafting head, external screw thread bellmouth joint, the flat shoulder grafting head Joint outer surface is provided with helicitic texture, and the clamp nut section is inverted L-shaped, and the boss coordinates with clamp nut and connected Connect, sealing ring is provided between flat shoulder grafting head and external screw thread the bellmouth joint, described external screw thread bellmouth joint one end is provided with External screw thread, the clamp nut is connected with flat shoulder grafting head, external screw thread bellmouth joint respectively by external screw thread respectively.
The beneficial effects of the utility model are:
1st, the utility model is simple in construction, dismounting and easy for installation, good airproof performance, is less prone to buckling deformation.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals:The flat shoulder grafting heads of 1-;2- clamp nuts;3- boss;4- external screw thread bellmouth joints;5- female ends; 6- sealing rings;7- external screw threads.
Embodiment
With reference to specific embodiment, the utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values also fall within application Appended claims limited range.
It is the utility model structural representation, a kind of inner liner stainless steel fitting pipe of the structure, including accessory referring to Fig. 1 Body, flat shoulder grafting first 1, clamp nut 2, sealing ring 6,5 both sides of female end of accessory body be respectively arranged with flat shoulder grafting first 1, Boss 3, the outer surface of boss 3 and the outer surface of external screw thread bellmouth joint 4 are provided with external screw thread bellmouth joint 4, flat shoulder grafting first 1 Be provided with helicitic texture, the section of clamp nut 2 is inverted L-shaped, boss 3 is connected with clamp nut 2, flat shoulder grafting first 1 with outside Sealing ring 6 is provided between threaded socket joint 4, the one end of external screw thread bellmouth joint 4 is provided with external screw thread 7, and clamp nut 2 is distinguished It is connected respectively with flat shoulder grafting first 1, external screw thread bellmouth joint 4 by external screw thread.
Female end 5 is enclosed on outside inner liner stainless steel pipe, and flat shoulder grafting first 1 is alignd with external screw thread bellmouth joint 4, flat key joint with Sealing ring 6 between external screw thread bellmouth joint 4 enhances its sealing.Clamp nut 2 is inverted l-shaped structure, and its vertical portion is abutted Screw thread is provided with the inside of the boss 3 of flat shoulder grafting first 1, its horizontal component, clamp nut 2 is connect by external screw thread 7 with external screw thread bellmouth First 4, flat shoulder grafting first 1 is spirally connected fixation, at this moment can ensure flat shoulder grafting first 1 and the sealing property of the junction of external screw thread bellmouth joint 4, Because clamp nut 2 covers the junction of flat shoulder grafting first 1 and external screw thread bellmouth joint 4, antileaking, is improved when in use Its sealing, it is also more convenient in dismounting, turn on clamp nut 2.Clamp nut 2 is generally parallel, will not be formed One larger projection, therefore the energy convenient use in placement, transport, installation process, it is overall parallel with pipeline, is difficult hair Raw buckling deformation.
